flutter macOS 流水账式填坑记录

2022-01-19

flutter-desktop

突然想学一下 flutter 开发桌面应用，想集成 desktop_webview_window 实现 electron 的功能。
遇到以下错误，流水账记录一下，希望有朝一日能帮到有缘人。

flutter 跑 mac 应用失败，对应错误如下：

$ flutter run -d macos

Launching lib/main.dart on macOS in debug mode...

      In Podfile:
        desktop_webview_window (from `Flutter/ephemeral/.symlinks/plugins/desktop_webview_window/macos`)

    Specs satisfying the `desktop_webview_window (from `Flutter/ephemeral/.symlinks/plugins/desktop_webview_window/macos`)` dependency were found, but they required a higher minimum deployment target.

画重点 CocoaPods could not find compatible versions for pod “desktop_webview_window”

解决办法

打开 $your_app_path/macos/Podfile
修改第一行 platform :osx, '10.11'
改成自己电脑的osx版本
比如我的电脑系统是这样的
mac-info
那我就改成 platform :osx, '12.1'

重新跑 flutter run -d macos
大功告成！

。。。并没有。。。

新错误：

又改成 platform :osx, '12.0.99'

又新错误

我明明已经设置成 12.0.99 了，这个10.11哪里蹦出来的。。

找到了
flutter-macos-error-snapshot-1

我又把它设置成 12.0.99，运行 flutter run -d macos 等待奇迹发生 🙏🙏🙏🙏🙏🙏

奇迹当然是没有发生啦，这种事怎么能祈求奇迹，只能靠我的聪明才智了

全局搜索 10.11

全局替换 12.0.99

flutter-macos-error-snapshot-2

💪💪💪💪💪💪💪 大力出奇迹，完成！！！
